Rank ReasonsAgrimonia parviflora is a perennial herb occurring along edges, in open spaces, thickets, deciduous or mixed woods, thickets in wet places, marshes, bottomland forests, and wet pastures of eastern North America from Ontario to Vermont south to Florida, west to Texas, and north to South Dakota in the United States, and in the Dominican Republic. It occurs as an introduced species in South America. There are over 2,000 estimated occurrences of this taxon range-wide, which are potentially threatened by development, rights-of-way maintenance, invasive species, grazing, succession, logging, recreation, and other threats in some places. Though considered rare on the northeastern edge of its range in North America, with a large range extent and large number of occurrences, Agrimonia parviflora is considered secure.
Range Extent CommentsThe native range of Agrimonia parviflora occurs in eastern North America from Ontario to Vermont south to Florida, west to Texas, and north to South Dakota in the United States (FNA 2014, NatureServe 2024, Weakley and the Southeastern Flora Team 2024). According to FNA (2014), it is also native to the Dominican Republic, but it is introduced in South America. Range extent was estimated to be over 2 million square kilometers using herbarium specimens, NatureServe Network occurrence data, and photo-based observations documented between 1993 and 2024, and over 4.4 million square kilometers when historical records from the Dominican Republic were included (GBIF 2024, iNaturalist 2024, NatureServe 2024, SEINet 2024).
Occurrences CommentsBy applying a 1 km separation distance to NatureServe Network data, photo-based observations, and herbarium records documented between 1993 and 2024, there are over 2,000 estimated occurrences rangewide (GBIF 2024, iNaturalist 2024, NatureServe 2024, SEINet 2024).
Threat Impact CommentsAlthough threats are not widely documented, Agrimonia parviflora is threatened by development, rights-of-way maintenance, invasive species, grazing, succession, logging, recreation, and other threats in some places (NatureServe 2024). However, their overall impact is likely negligible given the taxon's broad range, large number of occurrences, tolerance of light disturbance, and affinity for typically abundant habitats, as well as no obvious intrinsic vulnerabilities.
